Detectives are searching for two men from the Commodore who ran away without trying to help the maxi cab driver.

Assistant Commissioner Doug Fryer described their actions as gutless and un-Australian.

"People actually make mistakes and it's incumbent on everyone, should you make a mistake on the road, that you step up and look after your fellow Australian that you've just had a collision with," he said.

"For me, it is quite a gutless act and an un-Australian act to leave the scene of an accident leaving someone very seriously injured in the cab."

The pair are believed to be in their 20s and are of south-east European appearance.

One wore a white T-shirt and could have chest and facial injuries.

The other wore a black T-shirt.

The Commodore had false registration plates and police are making inquiries with the registered owner.

Anyone with information is urged to call Crime Stoppers on 1800 333 000.
